NET_Packet packet; uint32_t value; packet.r_u32(value);
NET_Packet packet; uint32_t value = 123456; packet.w_u32(value);This code writes a 32-bit unsigned integer value to an instance of NET_Packet. The value 123456 is stored in a variable called "value" and is written to the packet using the method "w_u32". Based on the syntax and naming conventions used in the examples, it is likely that NET_Packet is part of a network protocol library or framework. However, without additional information it is difficult to determine which specific library this code is using.
